I'm curious why no one has mentioned XLD; which I use on a Mac.
I had forgotten about TAG, and I thought xACT had been discontinued (maybe I was mistaken about that?)
I guess my own process adds an extra step, since I do all my audio processing on a PC (which is not allowed to be connected to the internet), and then I tag the files on a Mac.
Honestly, the only reason I do it that way is because the typing is a lot smoother on my Mac. I actually use the same model keyboard for the Mac and the PC, but I've always had a devil of a time trying to type on any PC compared to any MAC.
As for naming conventions, I'm pretty sure that's always going be somewhat subjective, based on whatever works best for each person's own collection.
Personally, for ease of finding things on my hard drives, I end up re-naming (but not re-tagging) a lot of whatever comes from other sources, because all my dates follow this format: 20220425 (no dashes or dots), and Artist Names are sorted by Last Name, rather than First Name. I try not to worry too much about the other info if a show came from someone else, because the name and date will generally do the trick when sorting or searching.
For what it's worth, my own convention goes like this:
Artist Name yyyymmdd Locale (City State Province Country etc) Venue
